<u>Answer:</u>

<em>D. The reverse reaction rate increases.</em>

<u>Explanation:</u>

The<em> rate of reverse</em> increases if the products are increased in a mixture at equilibrium.

At first,<em> rate of forward and backward</em> reactions are same for a <em>mixture in equilibrium. </em>

<em>If we add products or,the reaction moves to the opposite side I.e towards reactants side.</em>

so,according to the Le Chateliers principle,the reaction shifts opposite to the side of increase. so,according to the Le Chateliers priciple, <em>the rate of reverse or backward reaction will increase with the increase in the products.</em>

Electronegativity _____. generally increases moving from left to right across a period generally decreases moving from left to r
mojhsa [17]
I believe the correct answer would be that electronegativity generally increases moving from left to right across a period. The periodic table of elements is arranged so that trends of the properties of the elements can be shown. For electronegativity, it decreases from right to left which means for the opposite direction it increases.

Answer:

pH = 12.7

Explanation:

First, we have to calculate the [Ca²⁺] in a solution of about 250 ppm CaCO₃.

\frac{250mgCaCO_{3}}{L} .\frac{1gCaCO_{3}}{1000mgCaCO_{3}} .\frac{1molCa^{2+} }{100gCaCO_{3}} =2.5 \times 10^{-3} M

Now, let's consider the dissolution of Ca(OH)₂ in water.

Ca(OH)₂(s) ⇄ Ca²⁺(aq) + 2 OH⁻(aq)

The solubility product Ksp is:

Ksp = [Ca²⁺] × [OH⁻]²

[OH⁻] = √(Ksp/[Ca²⁺]) = √(6.5 × 10⁻⁶/2.5 × 10⁻³) = 5.1 × 10⁻² M

Finally, we can calculate pOH and pH.

pOH = -log [OH⁻] = -log (5.1 × 10⁻²) = 1.3

pH + pOH = 14 ⇒ pH = 14 - pOH = 14 - 1.3 = 12.7

How many moles are in 63 g of NH4 (molar mass= 18g)?
sdas [7]

To answer this question, all you to do is to divide the mass by the molar mass and that should get you your moles.

=63g\ NH_{4}\ x\ \frac{1\ mol\ NH_{4}}{18g\ NH_{4}}

<em>= 3.5 mol NH₄</em>

Which type of renewable energy creates electricity by using water currents to spin a turbine?
vovangra [49]

Answer:

Hydropower

Explanation:

I learn whenever Hydro is in a word it means water

Also in the question it is talking about water and wind, solar, nor Biomass has anything to do with water, so you can use the process of elimination and find you will only have Hydropower left.

Hope this helps
